* Instead ✨ **use `Union[SomeType, None]`** ✨.

Both are equivalent and underneath they are the same, but I would recommend `Union` instead of `Optional` because the word "**optional**" would seem to imply that the value is optional, and it actually means "it can be `None`", even if it's not optional and is still required.

I think `Union[SomeType, None]` is more explicit about what it means.

// - StorageClass "standard" has "1234 GiB" available in "topology.kubernetes.io/zone=us-east1"
// - StorageClass "localssd" has "10 GiB" available in "kubernetes.io/hostname=knode-abc123"
//
// The following three cases all imply that no capacity is available for
// a certain combination:
// - no object exists with suitable topology and storage class name
// - such an object exists, but the capacity is unset

   * all {@code a} of type {@code A} (and similarly for {@code reverse}). Note that a {@code false}
   * result from this method does not imply that the converters are known <i>not</i> to be
   * interchangeable.

can exhibit non-sequentially consistent executions.
In particular, note that a read <i>r</i> may observe the value written by any write <i>w</i>
that executes concurrently with <i>r</i>.
Even if this occurs, it does not imply that reads happening after <i>r</i>
will observe writes that happened before <i>w</i>.
